Let's divide 6400395 by 100
Let's see how many times 100 fits into 6400395.

Advancing to step 1:
The number 100 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 100

Moving on to step 2:
If we divide 64 by 100, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 100

Step 3:
When dividing 640 by 100, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 600 from 640, we get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 100

Going ahead to step 4:
When dividing 400 by 100, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 400 from 400 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 100

Moving on to step 5:
When dividing 3 by 100, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 640.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 100

Step 6:
39 divided by 100 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 6400.0
If we subtract 0 from 39, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 100

Step 7:
100 can be fit into 395 3 times, resulting in a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 64003.0
Deduct 300 from 395 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 8:
100 goes into 950 9 times with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 64003.9
If we take 900 away from 950, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 100 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 64003.95
Subtracting 500 from 500 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
100 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 64003.95
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 100 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 64003.95
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 64003.95 and a remainder of 0.0.
